What's going on everybody! Welcome
to today's video on the the network+
practice examination. My name is Jack Jenkins
and this is Academy of One. Today
in this eighth video, we're gonna be talking about TCP
slash IP. In this
video, I'm gonna be talking about
TCP and IP.

TCP or transmission control
protocol is responsible for
establishing mutual connections
between two nodes on a network.
An important thing to remember is that it is part
of the transport layer. Remember that for the test.
Another thing you should remember is that it uses a
three way handshake also known as
syn, syn-ack and ack.
Let's get a little more detail into this handshake.
So in this example, we have two nodes
or computers on the network. Bob
and alice. And bob wants to send
alice a file over FTP.
Now I know we haven't talked about FTP yet but we will in a
little bit. All you need to know is that it transfers files from
each other. And FTP uses TCP
to synchronize between the two
nodes. So first, bob is gonna
send alice an
acknowledgement or ack.
revive the synchronization packet
and if she wants she will send back a
synchronize acknowledgement saying yes, I
got the synchronization. Bob will then
send an acknowledgement of the
synchronized acknowledgment to alice
thus completing the three way handshake. A more
simple way to put this would be like if you and your
friend wants to go out to eat and you say hay! do you wanna
go to McDonalds. He says yes then I say are
you sure and he says yes.
That's sorta like the three way handshake in a
simpler more likely terms.

IP or internet protocol is
responsible for transporting data\
between two nodes.
more likely datagram as there called.
Now IP is
on the network layer, something you should remember
for the test. Now,I'm
not gonna be talking about IP addressing or
IP datagram layers or any of that.
That is for the networking tutorials.
Remember, the network+ that
this series is ment just to get you up to sped
for the exam. It's not ment to teach you everything you
need to know for computer networking. That's what the
networking class is for. I'm just
clarifying that cause there was some confusion about that.
TCP or transmission control
protocol is responsible for establishing
mutual connections within a
network. It uses something called a
three way handshake or
syn, syn-ack and ack.
And it is part of the transport layer.
Ip or
internet protocol is responsible for sending
datagram or just data.
Within the network. It is
part of the network layer
and you should remember the layers cause I
know for sure that that's on the test.
Time for the conclusion.
Uhm, you can go ahead and subscribe to us on youtube.
Go ahead and visit academyofone.org. And
lastly, go ahead and donate and please donate.
So in the next video we're gonna be talking
about TCP/IP
layer model. It's much like the
OSI model but it's for TCP
IP. Have a great day everyone.
